Overview

Creating and using strong passwords is an important part of your server/website security.

With Plesk 11, a strong password is required with your initial setup. These passwords are at least 8 characters long. Along with upper and lower-case characters, they require multiple occurrences of digits and special symbols. Such passwords provide strong protection from brute-force attacks.

Things to include

At least eight characters.

One or more of each of the following:

lower-case letter

upper-case letter

number

punctuation mark

Lookalike characters to protect against password glimpses. Examples:

O as in Oscar and the number 0.

Lower-case l and upper-case I.

The letter S and the $ sign.

Things to avoid

Words you can find in the dictionary.

Passwords shown as "example strong passwords."

Personal information, such as names and birth dates.

Keyboard patterns, like qwerty or 12345. Particularly avoid sequences of numbers in order.

Common acronyms.

All one type of character - such as all numbers, all upper-case letters, all lower-case letters, etc.

Repeating characters, such as mmmm3333.

The same password you use for another application.

Memorable password tips

While passwords that are easy for you to remember are also less secure than a completely random password, following these tips can help you find the right balance between convenience for you and difficulty for hackers.

Create a unique acronym for a sentence or phrase you like.

Include phonetic replacements, such as 'Luv 2 Laf' for 'Love to Laugh.'

Jumble together some pronounceable syllables, such as 'iv,mockRek9.'

Keep your password secret

Never tell your password to anyone (this includes significant others, roommates, coworkers, etc.). If you need to grant someone access to your server, set up a separate username and password for that person.
